PENCIL-SHARPENER.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed February 3, 1908. Serial No. 414,042.

To all 'whom 'it may concern:

Be it known that LWALTERTMACHALE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Pencil-Sharpeners, of which the following is a specification.

This invention relates generally to pencil sharpeners and more particularly to one in which the end of the pencil is drawn across the end of the sharpening blade, and the object of the invention is to provide an exceedingly simple, inexpensive and highly efficient form of Sharpener of this class, and one in which the pencil can not only be quickly and easily sharpened but also one in which either a long or short point can be had according to the degree of inclination at which the pencil is held with reference to the blade.

Another object of the invention is to provide a Sharpener of such construction that either a round or flat point can be produced as desired and a still further obj ect is to provide a encil Sharpener of such construction that al of the dust and dirt incidental to the sharpening operation will pass through the opening and be collected beneath the base so that it can be quickly and easily removed after the sharpening operation has been completed.

A still further object is to provide a simple and easy adjustment for the blade.

With these various objects in view, my invention consists essentially in the employment of a base having an opening through which the blade is adapted to project, said base being supported at one end by means of suitable legs, said legs having angular slots cut in the rear edges thereof, said angular slots being intended to receive the pivot lugs of a lever arranged beneath the base and carrying a blade, said blade projecting through the end of said lever, and also through the opening in the base, said lever and blade being securely fastened in the base at the desired point of adjustment by means of an adjusting screw passing through one end of the lever and bearing upon the adjacent end of the base.

The invention consists also in certain details of construction and novelties Ofcombination all of which will be fully described hereinafter, and pointed out in the claims.

In the drawings forming a part of this specification-Figure 1 is a perspective view of a pencil Sharpener constructed in :accordance with my invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a transverse vertical section. Fig. l is a top plan view. Fig. 5 is a detail perspective view of the lever. Fig. 6 is a detail lan view of the blade.

In the practicalpembodiment of my invention, I employ a base A having a transverse opening A adjacent one end, and this base is supported at said end by means of legs A2 the said legs being provided with angular slots A3 at their rear upper edges as shown. The base and legs are formed from a single piece of metal and any suitable metal may be employed and the base and legs may beforged or cast as preferred and it will, of-

course, be understood that the Sharpener will be made of various sizes. A lever B is arranged beneath the base, the forward end of said lever being curved as shown at B and provided with laterally projecting pivot lugs B2 which are journaled in the angular slots A3 thereby pivotally connecting the lever Within the base. The curved end of the lever B has a transverse opening B3 and the blade C is inserted through this opening at an inclination as shown and the cutting edge projected through the transverse opening A. A threaded opening B4 is produced in the rear end of the lever and a screw D working through this end bears upon the bottom face of the adjacent end of the base and serves to tightly bind the lever in the base and at the same time force the forward end of the lever up against the bottom face of the blade and tightly bind the top face of the blade against the lower edge of the transverse opening in the base, it being of course understood that when the rear end of the lever is brought downwardly, the forward end is necessarily forced upwardly and such movement will of course bind the blade tightly in the lever and also in the opening in the base. After the blade has been adjusted to the proper position, the end of the pencil to be sharpened is drawn across the said blade and of course bears upon the base and by holding the pencil at the proper angle any kind of point, a long or short one can be obtained and furthermore by sharpening from two faces only, a broad flat point can be obtained. All of the dust and dirt passes through the opening and collects under the base and after the sharpening operation has been com leted the Sharpener can be lifted and the dirt removed.

It will thus be seen that I provide an eX- ceedingly cheap, simple and ecient con-v struction of pencil Sharpener ycapable of -carrying out all of the objects hereinbefore referred to.

Having thus fully described my invention, what YI claim as new and desire to secure by Letters Patent, is

1. A pencil sliar ener comprising a slotted base provided wit supporting legs at one end, said legs having angular slots, a blade adapted to have its edge Vprojected through theslotted base, and a lever for holding said blade, said lever having laterally projecting pivot lugs, which enter the angular slots in the 4"legs, and an adjusting screw working through the rearend of said lever and bearing upon Vthe bottoni ofthe base, for the purpose ,set forth.

2. A pencil Sharpener comprising a base having an opening near one end, integral legs at said end, said legs being slotted, a blade, a lever -having an opening through which the blade asses, said lever being provided with lugs 'or engaging the slots in the legs, and means connected to the opposite -end Vof the lever Vfor adjusting the position of 3. A pencil Sharpener comprising a base having slotted legs, said base also having a transverse opening, a lever arranged below the base and provided with laterally lprojecting ivot lugs adapted to engage the slotted egs, the pivotal end of said lever having an opening, a blade arranged in said opening and projecting through the opening f1 in the base, and a screw carried at Vthe distal end of said lever, for the purpose.speciiied.V

4. A pencil Sharpener comprising .a base having an opening, a blade adapted to have one end projected through the said opening,

a lever pivotally connected to the base vupon Y the lower side thereof, said lever having an opening through which the blade passes and means carried by the lever for binding the blade against the lever and base, for the purpose set forth.
